COMBNED SHEARS AND CONVEYER FOR BILLETS.

SPECIFICATIQN forming part ofLetters Patent No. 455,074, dated June 30, 1891. Application filed July 18, 1890. Serial No. 359,146. (No model.)

To @ZZ whom t may con/cern.-

Be it known that we, FRANCIS H. TREAT and HORACE S. SMITH, both of Chicago, Cook county, Illinois, and CHARLES PETrIGREw, of

Joliet, Vill county, Illinois, have invented a new and useful Improvement in a Combined Shears and Conveyer, of which the following is a full, true, and exact description, reference being had to theaccompanying drawings.

Io Our invention relates to an improvement in duplex shears by which metal can be sheared alternately into determined length's or billets and the said billets automatically dropped from the duplex shears into a con- I 5 veyer, by which they are removed to the place of use.

Our invention will be readily understood from the accompanying drawings, in Which- Figure l represents a plan of our contrivzo ance, and Fig. 2 avertical section through the same.

The duplex shears and the particular form of conveyer here specified are shown in applications Serial Nos. 359,140 and 359,152,

this day executed by us, to which we referA for a fuller description 5 and we do not limit ourselves to these particular forms of shears and conveyers, except as specified in the claims herein, the object ot' our invention being to combine the duplex shears with a conveyer, so that the metal sheared from either shears shall be delivered upon the conveyer and automatically removed thereby.

A A A represent the rollers of a traiisfertable, to which the metal to be sheared is fed by the rollers B. Thistable is provided with a dividing-partition C, which directs the metal to either one of the shears K K alternately. The lower blades of these shears 4o are movable, and attached to them are the gage-stops E E', which are raised when the cylinders carrying thev shears are raised, thereby allowing the onward movement of the sheared metal by means of the rollers D D, which may be continuously operated, or operated whenever it is desired to forward the metal. In combination with the rollers D D is the chute F, wide enough to include the delivery from both shears, and open at the bottom, as at L, to deliver the billet upon 5o the conveyer-rollers G, which rollers being constantly operated remove the billets, and v they are fed through the opening L out of the way of the subsequentlyfalling billets. The shears K K are operated by any suitable mechanism alternately, so that while one is rising the other is falling. In this way the feeding oftwo billets simultaneously to .the chute F is prevented, which otherwise might fall in said chute and block the opera- 6o tion of the machine.

The operation of our machine can now be readily understood. The metal to be sheared is fed in upon the rollers B and directed by the switch D', under the control of the oper- 65 ator, as desired, to one side or the other of the partition C, and thence to the shears K or K', as desired. The metal is advanced by the rollers through the open shears, as shown at Fig. 2, until it is brought up against 7c the stop E. Then the shear-knife K, rising, cuts the billet, and at the same time removes the gage -stop E from its path of motion, so that it is fed onward by the rollers D D into the chute F, and thence through the opening L upon the conveyer rollers G G, by whichitiscontinuouslyremoved. VVhileone shears is operating to cut the metal the other is opening-to receive the subsequent metal to be cut. 8o

Vhat we claim as our invention, and desire to secure by Letters Patent, is-

l. The combination of the duplex shears and conveyer located beneath the level of the delivery of the metal and the chute receiving 8 5 the metal from both shears and delivering the same upon the conveyer, substantially as v described.

2. The combination, in duplex shears, of a conveyertable, a partition thereupon, a 9o switch for switching the metal to vone or the other ot' the duplex shears, the duplex shears, two gage-stops operated by the hydraulic cylinders and alternately raised from the path of the moving metal, a chute receiving the met-a1 when the said gage-stops and shears are operated, and the eonveyer beneath said tchute receiving the metal from both shears, substantially as described.

The combination of the alternately-operated duplex shears K K', the chute F F, having iaterallydnclned sides Wide enough to receive the metal from both shears, the opening L, and the eonveyer G beneath the `open- Io ing' L, substantially as described.
